MBC Lake Levels

Coalition for Equitable Water Flow (www.cewf.ca)

Our members have told us that the fluctuating water levels are a very important issue to them. These fluctuations affect boating, docks, fish spawning and loon nesting. For example by letting the water out too early all the Lake trout eggs on Mountain Lake were killed a few years ago.

Given the significance of this issue MBC is an active member and financial supporter of the Coalition for Equitable Water Flow, a volunteer organization that represents the interests of people like us on the reservoir and flow through lakes to the Trent Water System.

The TSW dams in Haliburton County are controlled and monitored by Parks Canada. You can see how things look at the various dams in our area by visiting their site at: www.pc.gc.ca/lhn-nhs/on/trentsevern.

The TSW will now be posting regular water level forecasts on their website. Click here – TSW Forecast – to see the latest.

It is important to note that a significant “drawdown” during a given period for lakes “upstream” of Maple and Beech Lakes ( in particular Redstone and Eagle Lakes ) could cause a temporary rise in water levels for MBC’ers.

Note, also, that rain or operational issues may affect the accuracy of these forecasts.  Make sure that boats and docks are secured appropriately if you will be away from the lake during a period of significant drawdown!

WATER LEVELS MEASURED AT MAPLE LAKE (Jan. 1, 2019 to July 18, 2019)

Water Level Forecast – July 16/19

Given the high temperatures, significant evaporation from large lakes, and lack of general precipitation over the Kawartha lakes and the reservoirs, the TSW has begun the drawdown of the reservoirs. This drawdown forecast indicates a significant draw on all the reservoirs to maintain lake levels downstream on the canal. All of the major rivers in the reservoir area should see some increase in flows. Although there is rain in the weather forecast it is for showers and thunderstorms and therefore may be hit and miss across the reservoir lakes with drought conditions continuing in some areas.
